Q: We are using QuickDraw 3D and are applying UV Attributes to our geometries so that we can texture-map. There are, however, two sorts of UVs - surface UVs and shading UVs. Which one do we need to set to get the textures to map correctly and what does the other one do?

A: Currently (QuickDraw 3D 1.0.4), only the surface UVs are supported. The shading UVs will be used in a future version to support advanced shading renderers.
